Beidseitig wirkender Antrieb für Verstellvorrichtungen

摘要

The invention relates to a drive acting on both sides for adjustment devices, comprising a rotationally mounted drive lever (10) for producing a rotational movement that can be selectively effected in one direction of rotation or in the other direction of rotation, a drive wheel (30) that can only be rotated when the drive lever (10) is moved from a zero point position, at least a one-piece coupling element (40) having two coupling areas (41, 41b) for transmitting a torque to the drive wheel (30), in addition to a sliding-block guide with areas for controlling the coupling element (40). The coupling element (40) can be displaced radially and is tiltably mounted in a guide (11) and coupled by both coupling areas (41a, 41b) in the zero position of the drive lever (10) to the drive wheel (30) in an elastic manner so that the non-loaded coupling area (41a, 41b) is uncoupled from the drive wheel (30) by the sliding-block guide when the drive lever (10) moves from the zero point position and remains uncoupled when the drive lever (10) moves in the opposite direction.
